Connecting UTP Cables | Cabletron Systems 100 specification

Unpacking and Installing Your ELS100-16TX

2.6.1 Connecting UTP Cables

Before connecting a segment to the ELS100-16TX, check each end of the segment to verify wire crossover.

Caution: To establish a link, you must have an odd number of crossovers (preferably one) between 10/100 BASE-T devices of the same type (i.e., from repeater to repeater or transceiver to transceiver).

Connect a twisted pair segment to the ELS100-16TX as follows:

1.Ensure that the device at the other end of the segment is connected to the segment and is powered ON.

2.Refer to Figure 2-5. Connect the twisted pair segment to the ELS100-16TX by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port.

3.Verify that a Link exists by checking that the port LINK LED is on (solid green). If the LINK LED is off, perform the following steps until it is on:

a.Check that the 10/100 BASE-T device at the other end of the twisted pair segment is ON and connected to the segment.
